は、既存のラインでは生産性が低下してしまう。In the plating layer of the metal plate 1, the thickness t 1 of the outer plating layer 3 is larger than the thickness t 2 of the inner plating layer 4. For example, in the hot-dip galvanized steel sheet, the outer surface side plating layer 3 has an adhesion symbol Z06 defined by the JIS standard and the inner side plating layer 4 has an adhesion symbol Z06 defined by the JIS standard that is the minimum required. Thus it is possible to use the amount of zinc is from about 60g less per plated steel plate 1 m 2,
It is economical. In addition, when used in severe open air where high durability and corrosion resistance are required, the saved zinc is stacked on the outer surface side plating layer 3 and the durability and corrosion resistance are maintained even when the total amount of zinc is the same. It is possible to manufacture an excellent heat insulating panel. The ratio of the amount of plating applied to form the outer plating layer 3 and the inner plating layer 4 is not particularly limited, but the upper limit of the amount of plating applied to form the outer plating layer 3 is 90 to 14.
It is preferably in the range of 0 g / m 2 . If the ratio exceeds this range, the workability such as the bending property may be reduced. On the other hand, the amount of plating for forming the inner surface side plating layer 4 is preferably in the range of 30 to 45 g / m 2 . 45
If it exceeds g / m 2 , no economic effect such as a reduction in cost can be expected. On the other hand, 30 g / m 2 is the minimum amount of plating in a normal plating method. In this line, the productivity is reduced.

The metal hoop material 1a which becomes the metal plate 1 in which the thickness of the outer plating layer 3 is larger than the thickness of the inner plating layer 4 is wound on the upper and lower payoff reels 5, 6, respectively. The metal hoop material 1a supplied from the payoff reels 5, 6 is bent at both ends or the center by the forming rolls 7, 8. Next, the metal hoop material 1 a is preheated to 20 to 50 ° C. in the preheating chamber 9, and thereafter, a hard urethane foam in which a polyol, an isocyanate, a catalyst, a foaming agent, etc. are blended between the metal hoop materials 1 a by the injection device 12. A foamable resin material such as isocyanurate foam or phenol foam is injected. Thereafter, while the metal hoop material 1a is carried in between the double conveyors 11 and moved, the metal hoop material 1a is heated within the range of 20 to 70 ° C., and the foamable resin material foams to form a space between the metal hoop materials 1a.

を図ることができる。Next, a urethane resin foam was filled between the two aluminum-zinc alloy-plated steel sheets to produce a heat insulating panel for a roofing material. The corrosion resistance of this heat insulating panel was measured. The results are shown in Table 1. Table 1 Bending performance Corrosion resistance (plated steel sheet / painted plated steel sheet) (Time) Example 1 0T / 8T 3000 or more 20T / 8T 3000 or more 30T / 8T 3000 or more 40T / 6T 3000 or more 50T / 8T 3000 or more 6 0T / 8T 3000 or more Comparative Example 1-3000 or more 2-3000 or more 3-3000 or more <Measurement method> Bending performance The number of identical plates inside the bend at the limit of peeling of the plating layer. The number of the same plate inside the bend at the limit of crack generation or peeling Corrosion resistance Time until the occurrence of red rust on the flat part by spraying with salt water As is clear from the results in Table 1, the bending performance of the example was At least it does not decrease,
In Examples 1, 3 and 5, the thickness of the outer plating layer is the same and the thickness of the inner plating layer is smaller than those of Comparative Examples 1, 2 and 3, respectively. Corrosion resistance is equivalent, and the cost can be reduced because the thickness of the inner layer is small.

とができるものである。According to the present invention, since the thickness of the outer plating layer of the metal plate is made larger than the thickness of the inner plating layer, the thickness of the outer plating layer is made the same as that of the conventional product. As a result, the same durability and corrosion resistance as those of the conventional product can be secured, and the total amount of plating is reduced, so that the workability is excellent and the cost is low. By attaching extra to the side plating layer, although the total plating adhesion amount is the same as the conventional product and the workability and cost do not change, the thickness of the outer side plating layer can be increased, and the durability and corrosion resistance can be improved. You can do it.
